Camden CM-9600 Illuminated Piezoelectric Push Button
The Camden CM-9600 is an illuminated piezoelectric push button designed for door strike and lock control in access control installations. Built on a heavy-duty stainless steel faceplate rated for weatherproof and vandal-resistant outdoor or high-traffic indoor environments, the CM-9600 eliminates moving parts through piezoelectric actuation—no mechanical switch means no wear-out cycles. The integrated illumination (red/green, field-selectable via jumper) provides immediate visual feedback, while the adjustable 40-second timer controls relay hold time for automatic door operators, electromagnetic locks, electric strikes, and request-to-exit (RTE) applications. Field-selectable N/O and N/C relay contacts rated 2A @ 30VDC support both fail-safe and fail-secure configurations in retrofit or new-build access control deployments.
Key Features
- Piezoelectric Actuation: No mechanical switch or moving parts. Eliminates contact wear and maintenance cycles across 10+ years of continuous high-traffic use.
- Stainless Steel Faceplate: IP66-equivalent weatherproof design. Suitable for exterior walls, high-moisture areas, and vandal-prone installations without additional protective housings.
- Field-Selectable LED Illumination: Red or green light via jumper. Provides user feedback during entry sequences and reduces confusion in high-volume pedestrian environments.
- Adjustable Hold-Time Timer: 0–40 seconds via potentiometer. Accommodates variable door operator dwell times without external timing relay.
- Dual-Contact Relay Output: 2A @ 30VDC, N/O and N/C modes jumper-selectable. Supports fail-safe and fail-secure lock configurations on the same device.
- 24VDC Operation: Standard 24VDC control voltage. Integrates with existing access control power infrastructure and strike controller circuits.
- Flush Single-Gang Mount: Designed for retrofit into existing electrical box openings. No external mounting hardware or surface-mounted enclosures required.
The CM-9600 integrates into standard access control system architectures where momentary or timed 24VDC push-button actuation is required. It pairs directly with door strike controllers, automatic door operators (both slide and swing), and electric lock systems that accept a 24VDC relay contact input. The piezoelectric design and stainless steel construction are particularly valuable in high-moisture or coastal environments where mechanical switches corrode quickly or in high-traffic areas (building lobbies, emergency exits, employee entrances) where switch fatigue becomes an operational burden. Unlike mechanical buttons that degrade after 100,000–500,000 actuations, the piezo element's sealed design is rated for millions of cycles without performance degradation.
Commissioning requires only 24VDC supply wiring, ground, and two relay contact conductors to the strike or lock circuit. All electrical configuration (LED color, relay mode, timer duration) is performed on-unit via jumpers and potentiometer adjustment — no software programming or external configuration interface. This simplicity reduces on-site integration time and lowers the skill barrier for field technicians unfamiliar with complex access control panels. The adjustable timer accommodates door operator hold-time requirements from a few seconds (automatic vestibule doors) to 40 seconds (high-security or ADA-compliant entry delays), making the unit a drop-in replacement across diverse door automation platforms.
The relay contact rating (2A @ 30VDC) is suitable for low-power strike control, electric strikes under 2A, and small electromagnetic locks. For heavier loads (e.g., full-size electromagnetic locks drawing 3–5A continuously), the CM-9600 output should drive a separate control relay or strike power supply rather than directly energize the lock. The stainless steel faceplate and piezo sealing require no special maintenance; standard electrical box installation practices (conduit entry, weatherproof box gaskets for outdoor use) are sufficient. Field selection of N/O or N/C contact mode allows the same hardware to serve both fail-safe (contacts open when power lost) and fail-secure (contacts held closed) access control strategies without hardware substitution.
The CM-9600 is a mature, field-proven component in access control architectures where a simple, maintenance-free push-button actuator is the right fit. Compliance with manufacturer warranty and standard 24VDC industry voltage ensure compatibility with entry-level through mid-range access control systems. Integrators evaluating this product should confirm that the 2A relay contact limit matches the downstream strike or lock power requirement, and verify that the adjustable timer range (0–40 seconds) aligns with the door operator's specified hold time.

In our experience, the CM-9600 fills a legitimate gap in access control hardware: a mechanically simple, vandal-resistant push button that doesn't require frequent maintenance or replacement. We've deployed these in office lobbies, parking garages, hospital employee entrances, and high-traffic commercial kitchens where mechanical push buttons routinely fail after 18–36 months of heavy use. The piezoelectric design is the real differentiator — there's no leaf spring, no moving contact arm, nothing to wear out or corrode. In coastal or humid environments, we've seen standard mechanical push buttons fail within months; piezo buttons in the same installations run trouble-free for 5+ years. The field-selectable LED (red vs. green) is also more thoughtful than it sounds — we've found that green provides better psychological feedback in mainstream commercial entry, while red is preferred in secure areas or data centers where red signals an access event. The adjustable timer is versatile enough to handle everything from quick vestibule access (3–5 seconds) to slow-moving ADA-compliant doors (30–40 seconds) without hardware swaps.
Technical Highlights:
- Piezoelectric Switch Element: No moving parts means zero wear-out under millions of actuations. Sealed against moisture and dust far better than mechanical contacts. In high-traffic retail or healthcare settings, this translates to near-zero unplanned downtime for button replacement over a 7–10 year lifecycle.
- Stainless Steel Faceplate: 300-series stainless steel resists corrosion in coastal, outdoor, and high-moisture environments. We've installed these in facilities where plastic or mild-steel buttons rust or discolor within a year — the stainless construction eliminates that aesthetic and functional degradation.
- Adjustable Timer (0–40 seconds): Potentiometer-based timing accommodates variable door operator dwell without external relay. In our projects, this flexibility has reduced hardware count on retrofit jobs and simplified training for facility staff who occasionally need to tweak hold times.
- Dual-Mode Relay (N/O + N/C): Jumper-selectable contact mode lets integrators use the same hardware for fail-safe and fail-secure configurations. We've reduced parts inventory and deployment time by standardizing on the CM-9600 across both strategies within a multi-building campus.
- 24VDC Standard Supply: Integrates seamlessly with legacy and modern access control panels. No power-supply compatibility issues or special conditioning required.
- Compact Flush Mount: Single-gang electrical box footprint. Retrofit installations don't require box expansion or surface-mounted enclosures, keeping labor cost down on older buildings.
Deployment Considerations:
- Relay contact rating is 2A @ 30VDC — confirm that your strike or electromagnetic lock draws less than 2A continuous. For full-size mag locks (3–5A), use the CM-9600 to drive a separate control relay or dedicated strike power supply; direct connection will cause relay dropout or failure.
- Timer adjustment is mechanical (potentiometer) — if door operators or facility staff need to change hold times frequently, document the potentiometer position or add a label inside the electrical box. Software-based timing is not an option with this hardware.
- LED illumination is field-selectable (red/green/off) via jumper on installation. Plan for this configuration during planning phases; changing it later requires opening the electrical box and removing the unit faceplate.
- Outdoor installations: while the piezo element and faceplate are weather-sealed, the electrical box itself must be rated for outdoor use (NEMA 4X or equivalent). Standard indoor boxes will allow moisture ingress around the wiring conduit.
- ADA compliance: if used in ADA-required accessible entry, verify that 40-second maximum hold time meets local code for your jurisdiction. Some jurisdictions require 50+ seconds for assistive device users.
The CM-9600 is the right product for integrators and facility managers who prioritize long-term durability and low maintenance over advanced features. If your project requires analytics, remote monitoring, or integration into a networked access control platform, this is a dumb device and should be paired with a dedicated access controller. But for retrofit, new-build, or replacement of worn mechanical push buttons in mid-to-low-traffic commercial and industrial installations, the piezo reliability and stainless construction deliver measurable ROI.
