Maintenance, Functional Testing, and Component Servicing

Non-Destructive Periodic Testing via SC070 Test Key

Routine regulatory inspection of the Morley-IAS HM-MCP-GLASS-AP addressable manual call point is conducted without fracturing the operative break-glass element. Maintenance personnel insert the dedicated SC070 specialist test key (supplied in packs of ten) directly into the aperture located at the bottom of the device housing. Inserting the key mechanically drops the internal glass retention carriage, releasing the internal micro-switch mechanism.

This action simulates an authentic manual activation, driving an immediate alarm condition across the Morley-IAS analogue addressable loop. Once transmission and panel response are confirmed, removing the SC070 test key automatically resets the internal micro-switch and repositions the glass carriage back to its standby position, eliminating downtime and unnecessary component waste during scheduled building safety audits.

Loop Diagnostics and Panel-Controlled LED Status Monitoring

Technicians can diagnose communication health directly at the device faceplate via the integral status LED, which is actively governed by the Morley-IAS fire alarm control panel:

• Normal Polling: The red LED blinks intermittently each time the fire alarm panel interrogates the addressable call point over the communication bus.
• Alarm State: Upon micro-switch release (via key test or physical glass break), the LED illuminates continuous, steady red to signal an active fire alarm condition.
• Current Consumption Verification: During loop electrical audits, technicians should measure an operating quiescent current of 80 µA at 24V DC (without communications active) and an alarm current draw of 130 µA at 24V DC (with active communications), operating within the allowable 15V to 32V DC supply voltage window.

Element Replacement: Glass (MUS155) and Resettable (PS230)

When the HM-MCP-GLASS-AP has undergone physical activation during an emergency event, the front break-glass element must be replaced to clear the panel latch and return the device to operational readiness. Replacement glass is available under manufacturer part code MUS155, supplied in packs of five glass elements.

For installations requiring a reusable operational surface, facilities may retrofit the call point with the PS230 flexible resettable element (supplied in packs of ten). The modular 'Plug & Play' assembly allows maintenance teams to access the front element retaining bezel quickly. During any front-cover disassembly or element swap, ensure the rotary decade switches on the rear of the unit remain set to their designated loop address before resealing.

Enclosure Inspection and Maintenance Parts Reference

The HM-MCP-GLASS-AP is constructed from durable PC/ABS engineering thermoplastic finished in RAL 3001 Red. Routine maintenance schedules should include a visual inspection of the housing to confirm enclosure integrity and ensure that the IP24D environmental seal is uncompromised across its -10°C to 55°C operating temperature and 10% to 93% non-condensing relative humidity rating.
